Factors affecting the accuracy of EWT - Misleading info

Question 1

What are the two AO3 PEELS to evaluate leading questions / misleading info as a factor affecting EWT?

Answer 1

Strength - prac apps
Weakness - lacks mundane realism

Question 2

P
(prac apps)

Answer 2

Strength - prac apps

Question 3

E

Answer 3

• this is bc the POT, that leading q can affect the acc of EWT has led to improvements in the criminal justice system such as the development of the cog interview
• which avoids using leading q and instead uses a variety of techniques to inc acc of EWT

Question 4

E

Answer 4

• e.g. uses open questions such as “recall everything about the event” to trigger as many details as possible to inc acc of EWT w out being affected by misleading info

Question 5

L

Answer 5

• therefore, the research i.a.i.p.o.a.p bc it could lead to more acc EWT + improve lives of ppl affected by crime

Question 6

Discussion

Answer 6

• Moreover, research could have pos impact on economy bc if EWT are more acc, this could lead to a quicker process to catch correct criminal
• therefore less taxpayers money is spent on multiple police interviews or re - trials, so this money can be used elsewhere to benefit society

Question 7

P
(lacks mundane realism)

Answer 7

However, a criticism - lacks mundane realism

Question 8

E

Answer 8

• this is bc L + P research uses artificial tasks such as watching vid of car crash

Question 9

E

Answer 9

• therefore it is difficult to gen findings of research that leading q do affect acc of EWT
• as watching a vid doesnt have the same importance consequences of giving inaccurate info for ppts to give acc EWT as compared to a real event

Question 10

L

Answer 10

therefore lowering ext val of research

Question 11

What are the two AO3 PEELS to evaluate post event discussion / misleading q as a factor affecting accuracy of EWT?

Answer 11

RTS - Skagerberg and Wright - film clip of mugging
Discussion - demand characteristics

Question 12

P
(RTS - Skaggerberg and Wright)

Answer 12

RTS - Skaggerberg and Wright

Question 13

E

Answer 13

• they showed ppts 2 versions of a mugging film clip, one where muggers hair was dark brown and another where it was light brown
• ppts then discussed clips in pairs but each of them have seen opp clips

Question 14

E

Answer 14

it was found that ppts didnt report what their co witness had seen but rather a blend of the two, so mugger had medium brown hair rather than dark or light

Question 15

L

Answer 15

therefore this supports bc it shows that memory contamination during post event discussion does occur and it can alter EWT rather than jus conforming to their co witness response

Question 16

P
(Discussion - demand characteristics)

Answer 16

However, much of the research investigating - may be affected by demand characteristics

Question 17

E

Answer 17

this is bc research is conducted in a controlled lab env with ppts doing unrealistic tasks like watching video clips of crimes

Question 18

E

Answer 18

• so ppts may have picked up on clues from task and worked out aim of the task
• so changed response to fit aim, to help researcher
• e.g. changing response to co witnesses after discussing clip

Question 19

L

Answer 19

therefore this lowers int val as the effects of discussing a crime on acc of EWT are not being accurately measured
